Four times as fast as a single person laying bricks on his own.
No comparison with laying concrete or tarmac.
"Tiger-Stone workers are able to lay out 400 square metres of new road every day"
Firstly there must be a substrate to lay the bricks on. Secondly, once the substrate is there then a tar cruncher or redi mix concrete machine should be able to match this.
Having just staggered outside in the cold and paced across our suburban street it is a good 8 paces wide. Say this equates to 7.5 metres. This machine can lay around 50 metres of surburban street a day once all the preparation has been done.
Amazing ground breaking invention?
Also, wouldn't it be cheaper just to employ four people?
